Review of the stick's increment 3 (a4221d8b..c416c805), on Captain Bob's word:
- check_images.sh deletes both images before building and makes each build a
check: a failed build left last run's lithos-pc.img in place, and every stick
check passed against it.
- mkartemis takes --first-lba and --sectors as plain decimal numbers only:
"abc", "-2", "2048x" and the like formatted at LBA 0, over the GPT.
- mkartemis --format reopens the image read-only and reads the volume back:
blk_commit_format ignores its own write errors, so a header that never
landed was reported formatted. The header is read from the disk and judged
as attach judges it (magic, version 2, BAM size); blk_get_volume_meta gives
the in-memory geometry of a blank disk, magic included, so --check no longer
relies on it either.
check_images.sh keeps each case as a check (40, PASS). stick_boot and datastick
on amd64/aarch64/riscv64 PASS on the rebuilt tools.

The stick's increment 3, Task 1 (docs/v4.0.0/plans/2026-10-27-stick-3-images.md;
STICK.md 4). make boot_image TARGET=PC now writes the 2 GiB stick: ESP 64 MiB
(BOOTX64.EFI, startup.nsh, starforth.cfg), StarshipOS identity 500 MiB (zeros),
StarshipOS Artemis to the end. make -f kernel/Makefile ARCH=<arch> datastick
writes the 1.5 GiB data stick, identity and Artemis, fresh every time. Sizes in
kernel/Makefile; every partition on whole MiB.
tools/mkartemis formats and signs an Artemis partition at build with the
kernel's own code -- v3's block_subsystem.c (blk_subsys_confirm_format) and
artemis_sig.c (artemis_sig_genesis_stamp) -- through a blkio device over a byte
range of the image; --check reads one back the same way (read-only). disk_uuid
from getrandom(2): each image its own. mkdiskimage.sh gains --starship,
--mkartemis, --esp-mib; Milk-V and the Pi images are unchanged. The kernel is
not changed.
Red: scripts/check_images.sh FAIL (no datastick, the PC image one partition).
Green: 23/23. Mutation: --check on a range shifted by one block fails.
Accepted: suite EXIT 0; 133146, 133417, 133815, POST 538/538, dict_hash
0xfec8c47cfc6f437f; test-32, 0 failures.
